This is a good product, i have used couple other products in the past and the quality is top notch. Well packaged,Easy install, pump is quite, water is clean! Would recommend 100%

I purchased the APEC tankless system, and its the most substantial upgrade I've made to my apartment and my quality of life in a decade. I appreciate the certifications and third party testing because the quality of my water isn't negotiable. The install was straightforward, the system is beautifully built, and the water iI get from it is incredible. All that's to say, I'm extremely satisfied, and offer my highest endorsement of this product and company.

I've had this system installed on a well water system for almost 4 years. It's a seasonal cabin but the usage is high when the the cabin is occupied. It's not just asking for a new filter. I thought this would happen 2 years ago. Way beyond expectations!

I installed the ROTL-AIO system at our northern MN cabin last month. The well water was unpleasant so gallons and pounds of water were brought in and the waste hauled out. The ROTL-AIO solved everything! The filtered well water tasted better than the bottled water and life is easier!! Installation was a little custom due to a cabin install but it just took a little longer.

I spent months researching the best tankless Reverse Osmosis system, in my opinion Apex has knocked it out of the park. Installation was a breeze. Love the extra space now in my cabinet and the unit looks fantastic. Most Reverse Osmosis system waste upwards of 10 to 1, are you serious? Ten gallons of water down the drain for one clean gallon? YEPS Now 2 gallons of clean to one gallon of waste water. It has enough water pressure to run my ice maker as well. You will hear noise from the pump when the unit is being used, nothing that it concerning.

We bought the unit a month ago and had some trouble with the power unit. APEC took care of it and the overall installation was a breeze. The water tastes amazing and gives us peace of mind since we're very concerned about forever chemicals (PFAS). Super happy with customer service and product.

Have been using my new APEC system for a couple weeks, and love it! No tank, so fits under sink nicely, and you only hear it when it is in use. I had a plumber install it, and he was impressed with it, too. It appears changing filters will be easy as well. Look forward to many years of pure water. R. David Campbell, M.D.

I've had this for a few weeks now and it works great. Super easy to install and use. My only complaint is that it sounds a bit like a jackhammer when it makes contact with the bottom of the cabinet and runs. Probably due to the area underneath being hollow and it amplifying the noise. Though this is the design of most cabinets. If they included a rubber/foam pad or something to help isolate it I think it would really help this. I've put a piece of foam underneath it and that really dulled the noise

Very pleased with this purchase. Takes up way less room than the previous unit that required a separate tank and the filter set up. Great flow. Only drawback is noise when in use. It is not very loud and only when in use. Single filter to replace will be great!

I replaced my RO-90 with the new ROTL-AIO. The new unit frees up a lot of under-the-counter-space. Nevertheless, it does not perform as well in filtering our water as the RO-90 did. The first water from the tap tests at 150 ppm. After running for thirty seconds, it will test at 30-35 ppm. When I disconnected the RO-90, the water tested at 22 ppm--on tired filters. With fresh filters, water samples test in the low teens. For reference, our Colorado river water test typically between 450 and 500 ppm, depending upon the season. I do like the faucet better on the R0-90. The extra inch-and-a-half in height made it easier to fill up my large pasta pot from the counter. The ROTL filter seems easy to install and remove, and much less messy that on the RO-90. The installation instructions are not very clear at several points. I'm glad I had experience installing an Ro-90. I am generally very impressed with APEC products. They seem well engineered and manufactured--well thought out from the consumer's perspective. The ROTL does not quite live up to these standards
